CTGS piezoelectric single crystal

The material that forms the core of our products, “Langasite type piezoelectric single crystal (CTGS),” was developed through joint research we conducted with the Yoshikawa Laboratory at the Institute for Materials Research, Tohoku University. It features a highly homogeneous crystal structure, which cannot be achieved with a conventional langasite crystal, and a chemical composition that minimizes the content of rare elements, making sustainable and low-cost development possible.

Langasite structure（general formula: A₃BC₃D₂O₁₄）

• Site A: Decahedron (8 oxygen cells)
• Site B: Octahedron (6 oxygen cells)
• Site C: Tetrahedron (4 oxygen cells)
• Site D: Small tetrahedron (4 oxygen cells)
